Which of the following bonds form through nonspecific attractive forces that arise when two molecules approach each other?
A
Ionic bonds
B
Hydrophobic effect
C
Van der Waals attractions
D
Covalent bonds
Verified step by step guidance1
Understand the nature of each type of bond or interaction mentioned in the problem.
Ionic bonds are formed through the electrostatic attraction between oppositely charged ions. They are specific and involve the transfer of electrons.
Covalent bonds involve the sharing of electron pairs between atoms, leading to a stable balance of attractive and repulsive forces between atoms.
The hydrophobic effect is not a bond but rather a phenomenon where nonpolar molecules aggregate in aqueous solutions to minimize their exposure to water.
Van der Waals attractions are weak, nonspecific forces that occur when molecules are in close proximity, due to transient dipoles that form as electrons move around the nucleus. These are the nonspecific attractive forces mentioned in the problem.
